Description

Technical Field

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

[0002] During clinical examinations in hospital obstetrics and gynecology departments or physical examination clinics, vaginal speculum is commonly used. Lubricant needs to be applied before use to facilitate easy insertion of the speculum's nozzle into the patient's vagina, allowing the doctor to perform subsequent examinations or treatments. Currently, most hospitals use manual lubricant application when using vaginal speculum. For example, a cotton swab can be used to apply bottled lubricant to the nozzle; or a tube of lubricant can be squeezed out and applied directly to the speculum; or a bag of lubricant can be used, where the speculum is inserted into the bag to absorb the lubricant. All of these methods have the following technical problems: inconvenient operation; lubricant dripping onto the worktable or floor during application, resulting in waste; and the worktable needs to be cleaned after each examination. Excessive application can also drip onto the patient's clothing, creating an unpleasant experience. To solve the above technical problems, vaginal speculum with built-in lubricant has been gradually developed (e.g., publication number CN212755600U). However, most vaginal speculum are disposable items, and the space in their duckbill structure is narrow. If lubricant is placed inside each vaginal speculum, the production is complicated and the manufacturing cost is high, which also leads to higher purchase costs.

[0003] Based on the above, the inventors developed a device that facilitates the application of lubricant, which can maintain cost reduction and solve the problems of existing technologies where applying lubricant to vaginal speculum easily leads to lubricant dripping and waste, and is inconvenient. Summary of the Invention

[0004] The present invention aims to provide a lubricant application device that can solve the technical problems of lubricant dripping, waste, and inconvenience in operation when applying lubricant manually.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lubricant application device includes a liquid storage cylinder with a liquid storage chamber inside. An elastic blocking element is provided inside the liquid storage chamber, and the blocking element has an opening that allows the liquid storage chamber to communicate with the outside. A top cover is also provided on the top of the liquid storage cylinder, and a sterilization device is provided on the top cover.

[0007] The principles and beneficial effects of this solution:

[0008] 1. By setting up a liquid storage cylinder and pouring lubricant into the storage cavity beforehand, when using the speculum, simply insert the speculum's prongs into the storage cavity through the opening of the blocking component and ensure full contact with the lubricant. This ensures that the lubricant is evenly applied to the speculum. Because the blocking component has a certain degree of elasticity, when the speculum is removed, excess lubricant on the speculum is blocked when it comes into contact with the blocking component, which can effectively prevent the lubricant from being carried out of the storage cylinder.

[0009] 2. By installing a disinfection device on the top cover, the liquid storage chamber can be disinfected after each use of lubricant by opening the cover, ensuring hygiene after use and avoiding cross-infection; when the liquid storage chamber needs to be cleaned, the disinfection device can also be used for comprehensive disinfection to ensure that the inside of the liquid storage chamber is hygienic and sterile.

[0010] 3. This application is convenient to use, simple to operate, and highly practical. When the device is placed in the gynecological examination room, it can be used for various medical devices that require lubrication. When using it, the device is directly inserted into the reservoir, which will not cause the lubricant to drip to the outside and avoid waste of lubricant.

[0011] In summary, the device provided in this application for facilitating the application of lubricant can solve the problems of lubricant dripping and waste caused by the inconvenience of manual lubricant application. Furthermore, this application has low production costs, is easy to use, and can be applied to most medical devices that require lubricant application. Moreover, it can be disinfected immediately after use, preventing cross-infection.

[0012] Preferably, as an improvement, the disinfection device includes an ultraviolet lamp and a display screen, with the ultraviolet lamp located on the inside of the top cover and the display screen located on the outside of the top cover.

[0013] Preferably, as an improvement, the top cover is also equipped with a power bank and a control button, the control button being electrically connected to the power bank, and the display screen and ultraviolet lamp also being electrically connected to the power bank.

[0014] Beneficial effects: The UV lamp can be turned on or off by controlling the power supply via the control button, and the display screen can show whether disinfection is in progress, making it easier for operators to observe more intuitively.

[0015] Preferably, as an improvement, it also includes a heating device, which includes a base and an electric heating tube and a temperature controller disposed at the bottom of the liquid storage tank. The base is provided with a power socket, which is electrically connected to the electric heating tube and the temperature controller. An external wire is also provided on the base.

[0016] Beneficial effects: By setting up a heating device, the lubricant can be heated, avoiding the cold feeling when the lubricant comes into contact with human skin. By heating the lubricant to a temperature close to human body temperature, the comfort of use is improved, and the patient's discomfort and anxiety are reduced. By setting up a temperature controller, the electric heating element can be intelligently controlled. Heating is started when the temperature is too low and stopped when the temperature is too high, ensuring that the lubricant is always at a suitable temperature.

[0017] Preferably, as an improvement, the base and the liquid storage tank are either integrated or detachably connected. This variety of design options broadens the applicability and provides users with greater choice.

[0018] Preferably, as an improvement, the reservoir is also equipped with graduation lines. These graduation lines allow the operator to visually observe the amount of lubricant in the reservoir, enabling them to select the appropriate amount to add based on actual needs, ensuring the lubricant is used up within the day and avoiding waste.

[0019] Preferably, as an improvement, the blocking component is a silicone ring, and a groove is provided on the inner wall of the liquid storage chamber. The silicone ring is connected to the groove by tension. Connecting the silicone ring by tension facilitates the installation and removal of the silicone ring and the cleaning of the liquid storage chamber. Attached Figure Description

[0025] The following detailed description illustrates the specific implementation method:

[0026] The markings in the accompanying drawings include: liquid storage cylinder 1, liquid storage chamber 10, scale line 11, arc groove 12, blocking element 2, groove 20, opening 21, retaining ring 22, mesh 23, anti-slip protrusion 24, top cover 3, display screen 31, control button 32, card slot 33, base 4, power socket 41, and wire 42.

[0027] Example 1

[0028] like Figure 1-2As shown, a lubricant application device includes a reservoir 1, a reservoir cavity 10 inside the reservoir 1, and graduation lines 11 on the reservoir 1; an elastic blocking member 2 is provided inside the reservoir cavity 10, and the blocking member 2 has an opening 21 that connects the reservoir cavity 10 to the outside. In this embodiment, the blocking member 2 is a silicone ring, and a groove 20 is provided on the inner wall of the reservoir cavity 10. The circumferential edge of the silicone ring is inserted into the groove 20 and tightened therewith; a top cover 3 is also provided on the top of the reservoir 1 for sealing the reservoir cavity 10. One end is hinged to the liquid storage cylinder 1, and the other end is fastened to the liquid storage cylinder 1. Specifically, the top of the liquid storage cylinder 1 is provided with a slot 33, which is a funnel-shaped structure. The top cover 3 is provided with an elastic buckle (not shown in the figure) that cooperates with the slot. The elastic buckle is made of silicone. When the cover is closed, the elastic buckle enters from the upper flare of the slot 33. The upper flare can play a guiding role and facilitate the insertion of the elastic buckle. Afterwards, the elastic buckle tightens in the slot 33 to seal the liquid storage cavity 10 and prevent dust, bacteria and other contaminants from entering and causing contamination of the lubricant.

[0029] The top cover 3 is also equipped with a disinfection device, a control button 32, and a power bank. The control button 32 is electrically connected to the power bank. Specifically, the disinfection device includes an ultraviolet lamp and a display screen 31. The ultraviolet lamp is located on the inner side of the top cover 3 (not shown in the figure), and the display screen 31 is located on the outer side of the top cover 3. The display screen 31 and the ultraviolet lamp are electrically connected to the power bank. In this embodiment, the power bank can be a rechargeable lithium battery or a disposable battery. The control button 32 is a touch button, including a power button and an adjustment button.

[0030] It also includes a heating device, which comprises a base 4 and an electric heating element and a temperature controller (not shown in the figure) located at the bottom of the liquid storage tank 1. In this embodiment, the base 4 is detachably connected to the liquid storage tank 1. Specifically, the base 4 is provided with a power socket 41, which is electrically connected to the electric heating element and the temperature controller. The base 4 is also provided with an external wire 42, which can be connected to a power source via a USB interface or directly via a plug to achieve heating. In this embodiment, by electrically connecting the temperature controller to the display screen 31, the current temperature in the liquid storage chamber 10 can also be displayed on the display screen 31, making it easier for the operator to observe the temperature of the lubricant more intuitively. By setting up a heating device to heat the lubricant, the cold feeling when the lubricant comes into contact with human skin is avoided. By heating the lubricant to a temperature close to human body temperature, the comfort of use is improved, and the discomfort and anxiety of patients are reduced. By setting up a temperature controller, the electric heating element can be intelligently controlled. Heating is started when the temperature is too low and stopped when the temperature is too high, ensuring that the lubricant is always at a suitable temperature.

[0031] The specific implementation process is as follows: Before using this device, the disinfection device can be opened to disinfect and clean the inside of the liquid storage chamber 10. Then, the lubricant is poured into the liquid storage chamber 10 and the top cover 3 is closed. The heating device is turned on to heat the lubricant, improving the comfort of subsequent use. Then, the prongs of the speculum are inserted into the opening 21 of the blocking member 2 to pick up the lubricant. Because the blocking member 2 has a certain elasticity, when the speculum is removed, the excess lubricant on the speculum is blocked when it comes into contact with the blocking member 2, which can effectively prevent the lubricant from being carried out of the liquid storage cylinder 1. In addition, due to the friction between the blocking member 2 and the prongs, the lubricant can be applied more evenly by the prongs. Finally, the speculum can be used directly after being removed. The lubricant application device of this application is convenient to use, simple to operate, can improve the efficiency of lubricant application, is applicable to a variety of medical devices, and is highly practical.

[0032] Example 2

[0033] The difference between this embodiment and Embodiment 1 is that, as Figure 3 As shown, the base 4 and the liquid storage cylinder 1 are integrated into one piece.

[0034] Example 3

[0035] The difference between this embodiment and Embodiment 1 is that, as Figure 4-5 As shown, the inner diameter of the upper chamber of the liquid storage cavity 10 is larger than the inner diameter of the lower chamber, and the blocking member 2 is installed at the step where the two meet; the inner wall of the bottom of the upper chamber of the liquid storage cavity 10 is provided with an outwardly extending arc-shaped groove 12. Figure 5 As shown, a deformable retaining ring 22 is provided on the outer side of the blocking member 2. The retaining ring 22 is inclined to cooperate with the arc-shaped groove 12. The retaining ring 22 is provided with anti-slip protrusions 24 and several mesh holes 23, and the mesh holes 23 are located near the outer edge of the retaining ring 22. When the blocking member 22 is installed, the retaining ring 22 will move towards the inner wall of the upper chamber of the liquid storage cavity 10. Figure 4 The two arrows on both sides converge inward, and the mesh 23 can provide space for the deformation of the retaining ring 22. At the same time, compared with the smooth surface, the mesh 23 can also increase the friction between the mesh and the groove wall of the arc groove 12, further reducing the tendency of the retaining ring 22 to slide out of the arc groove 12 when the lubricant is scraped off. In this embodiment, both the retaining ring 22 and the blocking member 2 are made of silicone.

[0036] During installation, first retract the retaining ring 22 inward, allowing it to enter the liquid storage chamber 10 and slide down its inner wall. When it reaches the arc-shaped groove 12, the outer edge of the retaining ring 22 gradually enters the arc-shaped groove 12. Then, squeeze the anti-slip protrusion 24, causing it to also enter the arc-shaped groove 12 and be positioned on the side of the arc-shaped groove 12 closest to the liquid storage chamber 10. This achieves both locking of the blocking component 2 and sealing of the arc-shaped groove 12. This installation method is simple and effectively prevents the blocking component 2 from falling off. When it is necessary to clean the inside of the liquid storage chamber 10, apply an upward external force to lift the blocking component 2 and remove the retaining ring 22 from the arc-shaped groove 12. Disassembly and assembly are convenient and the operation is simple.

[0037] Example 4

[0038] The difference between this embodiment and embodiments one, two, and three is that the liquid storage cylinder 1 is equipped with a removable liquid-holding inner liner, which makes it convenient to remove it for thorough cleaning, replenishment of liquid, and replacement.
