Description

Technical Field

[0001] This invention belongs to the technical field of obstetric drug delivery devices, specifically referring to an obstetric nursing cervical drug delivery device. Background Technology

[0002] Cervicitis is one of the most common gynecological diseases. It is an inflammation of the cervix, mainly caused by pathogen invasion or cervical injury. In the early stage, there may be no symptoms. As the disease progresses, patients will experience symptoms such as increased vaginal discharge, abnormal vaginal bleeding, vulvar itching, and dyspareunia. It is more common in women of childbearing age and is more prevalent among people with unsafe sexual practices.

[0003] Existing obstetric nursing cervical drug delivery devices typically administer medication via suppository insertion. However, the insertion site often fails to reach the cervix, rendering the medication ineffective. Even when the device reaches the cervix, it is difficult to provide a clear indication. Furthermore, vaginal disinfection and cleaning are necessary before medication administration, but existing cervical drug delivery devices lack automatic cleaning functions, making it impossible to complete the entire process of cleaning and medication administration. Therefore, a new obstetric nursing cervical drug delivery device is needed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a cervical drug delivery device for obstetric care, which effectively solves the problems of existing cervical drug delivery devices being unable to provide indication when reaching the cervix and being unable to provide automated operation for cleaning and drug delivery.

[0005] The technical solution adopted by this invention is as follows: This invention provides an obstetric nursing cervical drug delivery device, including an automatic switching drug storage mechanism capable of intermittent rotation, a drug delivery triggering mechanism, an operating base, a cross support frame, and a drive motor. The body of the drive motor is fixedly connected to the operating base, the cross support frame is fixedly connected to the operating base, the automatic switching drug storage mechanism is located on the operating base and the cross support frame, the drug delivery triggering mechanism is driven by the automatic switching drug storage mechanism, and the automatic switching drug storage mechanism is equipped with a pressure pump, thereby performing a cyclical operation of disinfection, cleaning, and drug delivery to achieve better therapeutic effects.

[0006] Preferably, the automatic switching drug storage mechanism includes a rotating shaft, a rotating drug storage cylinder, a partition plate, a lower drug delivery pipe, a lower connecting pipe, a lower locking groove, an upper connecting pipe, an upper discharging pipe, an upper locking ring, a built-in magnetic sheet, a top sealing cap, and a one-way valve. The rotating shaft is rotatably mounted between the operating base and the cross support frame. The rotating drug storage cylinder is fixedly connected to the rotating shaft. The partition plate is fixedly mounted in four groups around the rotating drug storage cylinder. The lower drug delivery pipe is connected to the top of the rotating drug storage cylinder. The lower connecting pipe is connected to the top of the lower drug delivery pipe. The lower locking groove is located at the top of the lower connecting pipe. The upper discharging pipe is connected to the cross support frame. The upper connecting pipe is connected to the bottom of the upper discharging pipe. The upper locking ring is located at the bottom of the upper connecting pipe. The built-in magnetic sheet is embedded in the lower locking groove. The top sealing cap is located on the cross support frame. The one-way valve is located on the top sealing cap.

[0007] Furthermore, the drug delivery triggering mechanism includes a main drug delivery tube, a drug delivery collar, an arc-shaped elastic element, a touch switch, and a cervical touch head. The main drug delivery tube is connected to one of the upper drug delivery tubes. The drug delivery collar is located at the top of the main drug delivery tube. The arc-shaped elastic element is arranged in a ring around the top of the drug delivery collar. The cervical touch head is fixed to the top of the arc-shaped elastic element. The touch switches are arranged in a ring around the bottom of the cervical touch head. Several sets of touch switches are connected in series. When the arc-shaped elastic element is deformed by force, it contacts the touch switch. The touch switch is electrically connected to the drive motor and the pressurization pump respectively. A small hole is provided through the cervical touch head.

[0008] Preferably, the drive motor and the pressurizing pump are controlled together by the controller. When the output end of the drive motor rotates 90 degrees intermittently, the upper locking ring is engaged into the lower locking groove through the built-in magnetic sheet, thus completing the delivery of disinfectant cleaning solution or cervical treatment drugs.

[0009] To reduce patient discomfort, the cervical os touch head is made of silicone and is cone-shaped.

[0010] Preferably, the arc-shaped elastic element is made of plastic and can be elastically bent at its centerline.

[0011] The upper locking ring is made of iron to cooperate with the built-in magnet.

[0012] Furthermore, the output end of the drive motor is connected to the bottom of the rotating medicine storage cylinder.

[0013] Furthermore, four sets of partitions divide the rotating medicine storage cylinder into four chambers, which are filled with disinfectant cleaning solution or cervical treatment drugs at intervals.

[0014] The pressure pump is divided into four groups located at the bottom of the rotating drug storage cylinder, which are used to control the administration of disinfectant cleaning solution or cervical treatment drugs in the corresponding cavities.

[0015] Furthermore, there are four sets of components: the lower drug delivery tube, the lower connecting tube, the lower locking groove, the upper connecting tube, the upper locking ring, and the built-in magnetic sheet spaced at 90-degree intervals. There are also three sets of components: the top sealing cap and the one-way valve. The top sealing cap is connected to three of the upper drug delivery tubes. This connection is used to link the top sealing cap and the upper drug delivery tube during the intermittent rotation of the rotating drug storage cylinder. The one-way valve only discharges gas, preventing the disinfectant and cleaning solution and cervical treatment drugs from spilling and thus preventing pollution of the surrounding environment.

[0016] To facilitate the delivery of disinfectant or cervical treatment medications, the lower delivery tube is located directly above the cavity.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: This solution provides a cervical drug delivery device for obstetric care, effectively solving the problems of existing cervical drug delivery devices being difficult to indicate when reaching the cervix and difficult to provide automated cleaning and drug delivery operations. This method brings the following advantages: (1) In order to solve the problem that existing cervical drug delivery devices are difficult to indicate when they reach the cervix, this invention proposes an automatic switching mechanism for the drug storage and drug delivery triggering mechanism. Only when the cervical touch head contacts the patient's cervix will the cervical touch head be unable to move forward, and the main drug delivery tube will drive the arc-shaped elastic element to produce a complete bending deformation. This not only provides medical staff with a method to indicate when the cervical touch head reaches the cervix, but also automatically triggers the operation of the drive motor and the pressurizing pump, providing an automated experience. (2) The four cavities are filled with disinfectant or cervical treatment drugs. The disinfectant or cervical treatment drugs in the four cavities are controlled by the four sets of upper locking rings being inserted into the lower locking grooves. This allows the disinfectant or cervical treatment drugs in the four cavities to be sprayed out from the end along the main drug delivery tube, thereby realizing the automated operation of cleaning-drug application-cleaning-drug application, which not only prevents bacterial growth but also improves the treatment effect.

Therefore, they should not be construed as limitations on this invention.

[0023] like Figures 1-3As shown, the present invention provides a cervical drug delivery device for obstetric care, including an automatic switching drug storage mechanism 1, a drug delivery triggering mechanism 2, an operating base 3, a cross support frame 4, and a drive motor 5. The body of the drive motor 5 is fixedly connected to the operating base 3, the cross support frame 4 is fixedly connected to the operating base 3, the automatic switching drug storage mechanism 1 is disposed on the operating base 3 and the cross support frame 4, the drug delivery triggering mechanism 2 is driven on the automatic switching drug storage mechanism 1, and a pressure pump 6 is provided on the automatic switching drug storage mechanism 1.

[0024] like Figure 1-Figure 5 and Figure 8 As shown, the automatic switching medicine storage mechanism 1 includes a rotating shaft 7, a rotating medicine storage cylinder 8, a partition plate 9, a lower medicine delivery pipe 10, a lower connecting pipe 11, a lower locking groove 12, an upper connecting pipe 13, an upper medicine outlet pipe 14, an upper locking ring 15, an internal magnetic sheet 16, a top sealing cap 17, and a one-way valve 18. The rotating shaft 7 is rotatably mounted between the operating base 3 and the cross support frame 4. The rotating medicine storage cylinder 8 is fixedly connected to the rotating shaft 7. The partition plate 9 is divided into four groups and fixedly mounted around the rotating medicine storage cylinder 8. The lower medicine delivery pipe 10 is connected to the rotating medicine storage cylinder 8. The top of the cartridge 8 is connected to the top of the lower delivery tube 10 via a lower connecting pipe 11. The lower engaging groove 12 is located at the top of the lower connecting pipe 11. The upper discharging tube 14 is connected to the cross support frame 4. The upper connecting pipe 13 is connected to the bottom of the upper discharging tube 14. The upper engaging ring 15 is located at the bottom of the upper connecting pipe 13. The built-in magnetic sheet 16 is embedded in the lower engaging groove 12. The top sealing cap 17 is located on the cross support frame 4. The one-way valve 18 is located on the top sealing cap 17. The upper engaging ring 15 is made of iron sheet.

[0025] like Figures 6-8 As shown, the drug delivery triggering mechanism 2 includes a main drug delivery tube 19, a drug delivery collar 20, an arc-shaped elastic element 21, a touch switch 22, and a cervical touch head 23. The main drug delivery tube 19 is connected to one of the upper drug delivery tubes 14. The drug delivery collar 20 is located at the top of the main drug delivery tube 19. The arc-shaped elastic element 21 is arranged in a ring around the top of the drug delivery collar 20. The cervical touch head 23 is fixed to the top of the arc-shaped elastic element 21. The touch switch 22 is arranged in a ring around the bottom of the cervical touch head 23. Several sets of touch switches 22 are connected in series. When the arc-shaped elastic element 21 is deformed by force, it contacts the touch switch 22. The touch switch 22 is electrically connected to the drive motor 5 and the pressurization pump 6 respectively. The cervical touch head 23 has a through hole. The cervical touch head 23 is made of silicone material and is conical. The arc-shaped elastic element 21 is made of plastic material.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the drive motor 5 and the pressurizing pump 6 are controlled by the controller. When the output end of the drive motor 5 rotates 90 degrees intermittently, it just happens to make the upper locking ring 15 lock into the lower locking groove 12 through the built-in magnetic sheet 16, thus completing the delivery of disinfectant cleaning solution or cervical treatment drugs.

[0027] like Figure 2-Figure 3 As shown, the output end of the drive motor 5 is connected to the bottom of the rotating medicine storage cylinder 8.

[0028] like Figure 1-Figure 2 As shown, four sets of partition plates 9 divide the rotating drug storage cylinder 8 into four chambers, and the four chambers are filled with disinfectant cleaning solution or cervical treatment drugs at intervals; the pressure pumps 6 are set in four groups at the bottom of the rotating drug storage cylinder 8 to control the administration of disinfectant cleaning solution or cervical treatment drugs in the corresponding chambers.

[0029] like Figure 4 , Figure 5 and Figure 8 As shown, there are four sets of components: the lower drug delivery tube 10, the lower connecting tube 11, the lower locking groove 12, the upper connecting tube 13, the upper locking ring 15, and the built-in magnetic sheet 16, spaced at 90-degree intervals. There are three sets of components: the top sealing cap 17 and the one-way valve 18. The top sealing cap 17 is connected to three of the upper drug delivery tubes 14, which is used to connect the top sealing cap 17 and the upper drug delivery tube 14 during the intermittent rotation of the rotating drug storage cylinder 8. Only gas is discharged through the one-way valve 18, so that the disinfectant cleaning solution and cervical treatment drugs will not spill, thus preventing pollution of the surrounding environment. The lower drug delivery tube 10 is located directly above the cavity.

[0030] In practical use, the patient's legs are crossed and spread open. The vagina is opened with a speculum forceps. The main administration tube 19 is held and inserted into the vagina. When the cervical touch head 23 contacts the protrusion inside the vagina, several sets of arc-shaped elastic elements 21 cannot fully deform, and therefore cannot contact all the touch switches 22. Because the touch switches 22 are connected in series, the drive motor 5 and the pressure pump 6 are not yet activated. Due to the cooperation of multiple sets of arc-shaped elastic elements 21 and touch switches 22, only when the cervical touch head 23 contacts the cervix and cannot move forward further will the main administration tube 19 cause the arc-shaped elastic elements 21 to fully bend and deform, ensuring all arc-shaped elastic elements 21 contact the touch switches 22, thus controlling the operation. The drive motor 5 and the pressure pump 6 operate, causing the output end of the drive motor 5 to rotate 90 degrees intermittently each time. This causes the upper locking ring 15 to engage with the lower locking groove 12 via the built-in magnetic sheet 16. The pressure pump 6 is activated when the upper locking ring 15 engages with the lower locking groove 12 via the controller. When the drive motor 5 starts again, the upper locking ring 15 disengages from the lower locking groove 12, and the pressure pump 6 shuts down. This process continues until the output end of the drive motor 5 rotates to 90 degrees again, at which point the upper locking ring 15 engages with the lower locking groove 12 again. This cycle repeats continuously. Through the cooperation of multiple sets of arc-shaped elastic elements 21 and touch switches 22, not only is a method provided for medical staff to indicate that the cervical touch head 23 has reached the cervix, but the operation of the drive motor 5 and the pressure pump 6 is also automatically triggered, providing an automated experience. The four cavities are filled with disinfectant or cervical treatment medication. The first cavity is filled with disinfectant. Initially, the corresponding built-in magnetic plate 16 engages the upper locking ring 15 into the lower locking groove 12. At this time, the first set of lower delivery tubes 10, upper delivery tubes 14, and main delivery tubes 19 are connected. The pressure pump 6 sprays the disinfectant from the first cavity along the main delivery tube 19, through the small hole on the cervical touch head 23, and onto the patient's cervix for disinfection and cleaning. After cleaning, the disinfectant flows out of the patient's body. The output of the drive motor 5 rotates the rotating drug reservoir 8 ninety degrees. The corresponding second set of built-in magnetic plates... When the upper locking ring 15 is engaged into the lower locking groove 12, the second set of lower drug delivery tubes 10, upper drug outlet tubes 14, and main drug delivery tubes 19 are connected. The pressurizing pump 6 causes the cervical treatment drug in the second cavity to be sprayed out from the end of the main drug delivery tube 19, acting on the patient's cervix for treatment. The disinfectant cleaning solution after cleaning flows out of the patient's body. The output end of the drive motor 5 drives the rotating drug storage cylinder 8 to rotate 90 degrees again. The disinfectant cleaning solution in the third cavity is then sprayed out from the end of the main drug delivery tube 19 for disinfection and cleaning again. This process is repeated to alternate between disinfection and cleaning of the patient's affected area and drug treatment, improving the treatment effect.
