Description

Technical Field

[0001] This utility model relates to the technical field of medical auxiliary products, and more specifically, to a medicated ointment. Background Technology

[0002] With the widespread adoption of Traditional Chinese Medicine (TCM) treatments, people often apply medicated plasters to specific acupoints to prevent or treat diseases. For example, people apply Sanfu plasters multiple times before and after the hottest days of summer (the "Dog Days of Summer"), or children, those with weak spleens and stomachs, or low immunity receive multiple applications to stimulate acupoints, unblock meridians, adjust the body's Yin-Yang balance, enhance immunity, and treat chronic diseases. The plasters are prepared fresh for each use. Medical staff typically prepare the plasters in advance, taking out a new plaster before each application, manually applying the plaster to the corresponding acupoint. Each application usually requires a dozen or more plasters. Manually applying the plaster is time-consuming, and the amount applied is entirely up to the medical staff, which can easily lead to dosage errors—too much plaster is wasteful, while too little affects the treatment effect.

[0003] Existing syringes for assisting in the quantitative dispensing of liquids include patent number ZL 202121875339.8, entitled "A Quantitatively Propellable Syringe." This syringe achieves quantitative injection of medication by setting a quantitative control mechanism next to the syringe. However, this syringe can only perform one quantitative injection at a time and cannot achieve multiple quantitative dispensings, thus failing to meet the requirements for quantitative dispensing of ointments. Therefore, there is an urgent need to design a device to assist in applying medication ointments to solve the above problems. Utility Model Content

[0014] Furthermore, the syringe is provided with an injection head on the outside of the injection port. The upper end of the injection head is sleeved and fixed to the injection port of the syringe, and the lower end of the injection head is provided with multiple ointment injection outlets.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model discloses a medicated plaster application device. It utilizes a syringe fixing ring and a push rod fixing plate. The syringe fixing ring is fixed to the outside of the syringe barrel, and the push rod fixing plate secures the outer end of the syringe push rod. A pair of transverse support rods are symmetrically arranged on the outside of the syringe fixing ring. A pair of metering rods are symmetrically arranged between the syringe fixing ring and the push rod fixing plate. The upper ends of the metering rods are fixedly connected to the push rod fixing plate. Each of the transverse support rods has a through hole, and the lower ends of the metering rods pass through the through holes and extend below the transverse support rods.

When using this medicated plaster application device to apply medicated plaster, the syringe... The fixing ring and the push rod fixing plate are respectively fixed to the syringe barrel and push rod of the syringe filled with ointment. The medical staff pushes the syringe push rod towards the injection port. The metering rod, which is fixedly connected to the push rod fixing plate, will move synchronously with the movement of the push rod. The retaining rings on the metering rod deform one by one along the direction of movement and enter the through hole. As the retaining rings enter the through hole, they stop the movement process. When the medical staff feels the resistance of each push, they can know that a certain amount of ointment has been injected into the medicated patch. When a new ointment needs to be applied, they push the syringe push rod forcefully to release the resistance of the current retaining ring and continue to move forward until the next retaining ring enters the through hole. In this way, the ointment can be applied repeatedly, which is convenient, accurate, and efficient. Attached Figure Description

Detailed Implementation

[0025] The technical solution of this utility model will be further described in detail below with reference to specific embodiments, but this does not constitute any limitation on this utility model.

[0026] Reference Figures 1 to 6 As shown, this utility model discloses a medicated plaster application device, including a syringe barrel fixing ring 2 fixed to the outside of the syringe barrel of a syringe 1 and a push rod fixing piece 3 fixed to the outside of the push rod of the syringe 1. The syringe barrel fixing ring 2 has an open structure, and first fixing screws 4 are provided on both ends of the syringe barrel fixing ring 2. The first fixing screws 4 pass through one end and are threaded to the other end. When it is necessary to insert the syringe barrel of the syringe into the syringe barrel fixing ring 2, the first fixing screws 4 are unscrewed to insert it through the opening of the syringe barrel fixing ring 2. When it is necessary to fix the syringe barrel fixing ring 2 to the outside of the syringe barrel, the first fixing screws 4 are inserted into the insertion hole and screwed to lock the opening of the syringe barrel fixing ring 2. A pair of transverse support rods 5 are symmetrically arranged on the outer side of the syringe fixing ring 2. A pair of metering rods 6 are symmetrically arranged between the syringe fixing ring 2 and the push rod fixing plate 3. The upper ends of the pair of metering rods 6 are fixedly connected to the push rod fixing plate 3. Each pair of transverse support rods 5 is provided with a through hole 7. The lower ends of the pair of metering rods 6 pass through the pair of through holes 7 and extend below the transverse support rods 5. Multiple elastic retaining rings 8 are evenly arranged on the surface of the pair of metering rods 6 along their extension direction. The diameter of the through hole 7 is adapted to the diameter of the retaining ring 8. By utilizing the mutual cooperation between the through hole 7 and the retaining ring 8, when the retaining ring 8 moves with the metering rod 6 to the through hole 7, the retaining ring 8 deforms and enters the through hole 7, forming resistance and preventing further movement. This allows medical personnel to perceive and achieve quantitative injection of ointment, making it convenient to use and accurate in medication application. Multiple retaining rings 8 can sequentially enter and exit the through hole 7 to achieve the effect of multiple quantitative injections of ointment, resulting in high work efficiency. The elastic retaining ring 8 can be a specific elastic object such as a rubber ring. The volume of ointment injected each time is about 1 mL, which is the most suitable amount for applying the ointment.

[0027] Furthermore, a fixing plate 9 is provided directly below the syringe 1, and a pair of support plates 10 are symmetrically arranged above the fixing plate 9. A vertical rod 11 is provided between the pair of support plates 10 and the fixing plate 9. Each pair of support plates 10 is provided with a fixing slot 12. The bottom of the pair of horizontal support rods 5 is provided with an insertion rod 13. The upper end of the pair of insertion rods 13 is fixedly connected to the horizontal support rod 5, and the lower end of the pair of insertion rods 13 is inserted into the fixing slot 12. By utilizing the cooperation between the fixing slot 12 on the support plate 10 and the insertion rod 13 at the bottom of the horizontal support rod 5, the syringe barrel fixing ring 2 holding the syringe can be fixed on the pair of support plates 10. When applying the medicated plaster, the medicated plaster is placed on the fixing plate 9, directly below the injection port. Medical staff only need to use one hand to press down the syringe plunger to push the medicated plaster out of the syringe, and the other hand can be used to do other work such as changing the medicated plaster on the outside of the injection head, which improves work efficiency. Each of the vertical rods 11 is provided with a buffer structure between itself and the fixing plate 9. When medical staff push the plunger of the syringe downwards, the buffer structure allows the syringe to move down until the injection head contacts the medicated plaster directly below it, so that the plaster can be injected onto the medicated plaster.

[0028] Furthermore, the buffer structure includes a guide cylinder 14 vertically mounted on the fixed plate 9. The lower part of the vertical rod 11 is slidably installed in the guide cylinder 14. A spring 15 is provided between the vertical rod 11 and the bottom of the guide cylinder 14. When medical personnel push the plunger of the syringe downward to drive the syringe as a whole, the support plate 10, and the vertical rod 11 to move downward, the vertical rod 11 presses down to deform the spring 15 until the injection port of the syringe touches the medicated plaster placed on the fixed plate 9, so as to achieve the effect of contacting the injection port with the medicated plaster.

[0029] Furthermore, the push rod fixing plate 3 is provided with a push rod slot 16. The groove of the push rod slot 16 is in the same direction as the opening of the syringe fixing ring plate 2, which facilitates fixing the outer end of the syringe push rod in the push rod slot 16 and pushing the syringe syringe into the syringe fixing ring plate 2, so that the syringe syringe is fixed by the syringe fixing ring plate 2 and the push rod is fixed by the push rod fixing plate 3.

[0030] Furthermore, clamping plates 17 are provided on both sides of the slot of the push rod slot 16, and a second fixing screw 18 is provided between a pair of clamping plates 17. The second fixing screw 18 passes through one of the clamping plates 17 and is threadedly connected to the other clamping plate 17. When it is necessary to insert the syringe push rod into the push rod fixing plate 3, the second fixing screw 18 can be unscrewed to insert it from the opening of the push rod fixing plate 3. When it is necessary to fix the push rod fixing plate 3 to the outside of the syringe barrel, the second fixing screw 18 is inserted into the insertion hole and screwed to lock the opening of the push rod fixing plate 3.

[0031] Furthermore, the inner wall of the syringe fixing ring 2 is provided with a rubber pad 19 to increase the friction between the syringe fixing ring 2 and the syringe barrel, thereby enhancing the fixing effect.

[0032] Furthermore, the bottom of the fixing plate 9 is provided with an anti-slip pad 20 to increase the friction between the fixing plate and the tabletop and prevent slippage when applying the medication.

[0033] Furthermore, a buffer pad 21 is provided on the upper part of the fixing plate 9. The buffer pad 21 is located directly below the injection port of the syringe 1. The buffer pad 21 can buffer the pressure applied by the injection head and prevent damage to the injection head due to excessive force. A marking point is provided in the center of the buffer pad 21 to remind medical staff of the optimal position for placing the medicated plaster.

[0034] Furthermore, the syringe 1 is equipped with an injection head 22 on the outside of its injection port. The upper end of the injection head 22 is fitted and fixed to the injection port of the syringe 1, and the lower end of the injection head 22 is provided with multiple ointment injection outlets 23. The injection head 22 and the ointment injection outlets 23 allow for more dispersed injection of the ointment into the medicated plaster, ensuring effective application. The lower end of the injection head 22 has various diameters to facilitate application to medicated plasters of different widths. The number of ointment injection outlets 23 on the injection head 22 decreases as the diameter of the lower end of the injection head 22 decreases, ensuring that injection heads of different sizes can evenly apply the ointment to the medicated plaster.

[0035] Before using the ointment application device of this utility model, medical staff first fill the syringe with ointment. When the ointment needs to be applied, the medical staff places the ointment outside the injection port of the syringe, and then places a new ointment outside the injection port of the syringe. The syringe plunger is pushed towards the injection port, and the metering rod 6, which is fixedly connected to the plunger fixing piece 3, will move synchronously with the movement of the plunger. The retaining ring 8, which is closest to the through hole 7 along the movement direction of the metering rod 6, will move into the through hole 7. As the retaining ring 8 enters the through hole 7, the elastic retaining ring 8 deforms, thereby generating resistance to prevent the movement process. At this time, the medical staff feels the resistance to the push and can sense that a certain amount of ointment has been injected into the ointment. Afterwards, the medical staff can replace the ointment with a new one outside the injection port and push the syringe plunger again to push out the retaining ring 8 in the through hole 7 until the next retaining ring 8 enters the through hole 7. Its deformation generates resistance to prevent the movement process, and the metered ointment can be injected again.

[0036] Furthermore, the syringe with the fixed syringe retaining ring 2 is fixed to a pair of support plates 10. Specifically, the insertion rods 13 on the pair of horizontal support rods 5 are respectively inserted into the fixing slots 12 on the pair of support plates 10. Pushing the syringe plunger towards the injection port, the buffer structure causes the syringe to move downwards, bringing the injection head into contact with the medicated plaster directly below it. If the medical staff continues to push the plunger, it will move towards the injection port within the syringe until the retaining ring 8 closest to the through hole 7 enters the through hole 7. The deformed retaining ring 8 creates resistance in the through hole 7, allowing the medical staff to sense that a dose of medication has been administered. Releasing the force on the plunger, the spring 15 returns to its original shape, causing the vertical rod 11, support plates 10, and the syringe to move upwards, disengaging the injection port from the fixing plate 9. The medical staff can then replace the medicated plaster below the injection head 22. If the plaster is stuck to the injection head 22, it can be easily pulled out.

[0037] The above description is only a preferred embodiment of the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
